When thinking of George A. Romero's Dawn of the Dead, words like classic or masterpiece instantaneously come to mind. Not only is it one of the best zombie flicks ever made but it is also a must see for everyone who does not hate the zombie genre. There are many versions but the two most important ones are the US Theatrical Version (aka "Romero Cut") and the European Theatrical Version (aka "Argento Cut"). But over the years, several other versions had been edited which brings me to this comparison. One of said versions is the so-called Extended Cut (aka Cannes Cut") which - as already implied by its name - is a longer version that had been edited by Romero himself in order to show this masterpiece in Cannes. It is also known as "Director's Cut" but frankly, I find that name a little confusing since both the US Theatrical Version and the Extended Cut are versions edited by Romero himself. Despite the length difference of 12 minutes, the differences between the US Theatrical Version and the Extended Cut are not that huge. The additional plot is nice, especially the scenes inside the mall, and there is a bit more violence as well but that is it. All in all, the US Theatrical Version definately does the trick but the Extended Cut is a nice addition for fans.

Additional Scene03:02 / 03:02

The TV discussion about how to handle the bodies is longer. To be more specific, Dr. Foster's statement is longer.
Dr. Foster: "A dead body must be exterminated either by destroying the brain or severing the brain from the rest of the body."
The people at the studio are upset about his statement. As a result, the doc addresses them directly.
Dr. Foster: "The situation must be controlled before it's too late."
Due to the upset people, one can only hear the last words of the doc's subsequent comment: "…multiplying too rapidly!"

17.3 sec

Additional Scene04:42 / 04:59

After Stephen's arrival at the studio, there is an additional comment by the doc - including an intercut to Mr. Berman.
Dr. Foster: "Should we be unable to check the spread because of the emotional attitude of the citizens because issues of morality."

6.7 sec

Additional Scene / Recut / Alternate Audio Track05:01 / 05:25

Additional shot of Dr. Foster.
Dr. Foster: "(Citizens will be moved in the central areas of the city.) The bodies of the dead will be delivered over to specially equipped squad of the national guard (to organize disposition)."
Slightly afterwards, this additional shot is also in the US Theatrical Version as alternate footage but I will get to that.

On a related note, I would like to point out that the audio differs as well: The dialog in brackets is audible during the identical shots of Francine and Mr. Berman. Then the additional shot of Dr. Foster, followed by a shot of Stephen and some other people during which the last words of Dr. Foster are audible (also in brackets).

In the US Theatrical Version however, one now gets to hear Dr. Foster's comment which had been used slightly earlier in the Extended Version (please see 03:02 / 03:02): He explains what to do with the bodies. This goes for both the footage before and after the additional shot of Dr. Foster. In other words: In the US Theatrical Version, said comment is audible during the shots of Francine, Mr. Berman and Stephen.
Dr. Foster (aus dem Off): "A dead body must be exterminated either by destroying the brain or severing the brain from the rest of the body."

US Theatrical Version

Extended Cut

6,2 sec

Alternate Footage / Recut / Alternate Audio Track05:40 / 06:11

The US Theatrical Version here contains the shot of Dr. Foster from the Extended Version (please see 05:01 / 05:25).
The Extended Version contains his following comment - the part is brackets is off-screen though resp. audible during the two previous and the subsequent shots.
Dr. Foster: "(Citizens will be moved in the central areas of the city.) The bodies of the dead will be delivered over to specially equipped squad of the national guard (to organize disposition)."

The US Theatrical Version lacks both the beginning and ending of that. To be more specific, the US Theatrical Version only contains the bold-marked part of the comment plus the Doc only speaks the underlined part on-screen. The previous part is audible during the previous shot of Francine (in the Extended Version, one only gets to hear indistinct comments from the crowd in the background).
Dr. Foster: "Citizens will be moved in the central areas of the city. The bodies of the dead will be delivered over to specially equipped squad of the national guard to organize disposition."

In the Extended Cut, an additional shot of the moon follows the already mentioned shot of Francine (which for the record is 0.4 sec longer in the Extended Cut). Compared with the shot of Dr. Foster, the shot os the moon is slightly shorter - hence the insignificant length difference we have here.
